Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.
States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.
Hypothesis: Contractors need faster repeat invoices more than more templates.
First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.
The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.
Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

twinme+ is a premium version of twinme private messenger, a secure instant messaging and High-Definition voice/video call application, protecting privacy by design, and giving users full control over each of their relations and exchanged content. In addition to all the functions and services offered by twinme, twinme+ offers the following features: - "Spaces" to organize your profiles, relations, conversations, notifications, appearance and parameters, according to each social group you interact with. Different Spaces can be used for interacting with your family, friends, colleagues, sport mates, etc.; You can even create "Secret Spaces", which do not appear in the list of Spaces and can only be opened by typing their name (do not forget that name as it will be impossible to retrieve); - "Ephemeral messages", ie messages which disappear at both ends after a certain time; - Option to lock/unlock the application using your device biometric or pin locking services; - Option to prevent a contact from making voice/video calls; - Streaming your music during calls; - Launching group calls; - Inviting additional contacts to join an on-going voice/video group call; - Transferring an on-going voice/video call from a mobile to a PC; - Publishing QR-codes from the calls tab that allow guests to call you without installing the application (click-to-call). If twinme is already installed on your device, your twinme account will be automatically transferred with all its associated data (contacts, conversations, etc.) to twinme+ and you can then uninstall twinme from your device. If you had defined several profiles in twinme, each one will be associated with a different Space. You can then move contacts to your Space of choice. Thank you for contributing to the development of twinme. twinme uses your device Internet connection (WiFi or 3G/4G/LTE as available). Data charges may therefore apply. Check your carrier for details. PERMISSIONS: . “Camera” & “Microphone” to take pictures, make voice/video calls . "Photos" for profiles and to send/receive photos in messages . "Notifications" to be notified of calls and messages . "Background App Refresh" to receive calls and messages while app sleeps in the background . "Mobile Data" to be able to make and receive calls and exchange messages.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
